摘要: Nickel posphite (Ni11(HPO3)8(OH)6) hexagonal polyhedrons are successfully synthesized under hydrothermal conditions. The effect of surfactants on the growth mechanism Ni11(HPO3)8(OH)6 also explored. More importantly, applied as electrochemical supercapacitor electrode materials, which have a good specific capacitance (295 F g−1 at 0.625 A g−1), rate capability, and cycling properties (maintained about 99.3% after 1000 cycles).
